Description

Technical Field

[0001] This utility model relates to the production and processing of flexible chips, and in particular to a material handling mechanism that works in conjunction with a metal strip unwinding mechanism. Background Technology

[0002] In flexible chip bonding and placement, a typical design involves one cell loading process, one ribbon loading process, and a matrix placement machine. Cell materials undergo processes such as drilling, dispensing, photocuring, and silver paste application. Ribbons undergo processes such as cutting, coding, drilling, dispensing, photocuring, and silver paste application. The ribbon, a metal strip, is wound onto a reel and unwound by a strip unwinding mechanism. The unwound strip needs to be cut and transferred to the next process by a material handling mechanism. Current material handling mechanisms typically include: a mechanism to move the strip and a scissor module for cutting; and a three-axis module-controlled robotic arm for transfer. Current material handling mechanisms are relatively complex, involving multiple steps in the cutting and transfer process. Utility Model Content

[0034] The following description is provided in conjunction with the accompanying drawings, which are for illustrative purposes only and not strictly to scale. Unless otherwise defined, the technical or scientific terms used in this disclosure should be understood in their ordinary sense by one of ordinary skill in the art to which this disclosure pertains.

Unless otherwise specified, the embodiments in this application can be combined with each other.

[0035] Please see Figure 1, Figure 2 and Figure 3 A material handling mechanism that works in conjunction with a metal strip unwinding mechanism 7 includes: a first mounting part 1, a three-axis moving module 2, two material handling grippers 3, a first finger cylinder 4, a scissor module 5, and a first drive cylinder 6.

[0036] The material handling mechanism pulls the metal strip 8 out of the reel of the metal strip unwinding mechanism 7. The pulled-out metal strip 8 is horizontal. For the convenience of subsequent description of the orientation, the direction in which the metal strip 8 is pulled out is set as the first direction.

[0037] The first mounting part 1 is used to install on the equipment frame of the metal strip unwinding mechanism 7. The mounting position of the first mounting part 1 is in the first direction, and the metal strip 8 pulled out from the coil passes through the first mounting part 1.

[0038] The three-axis moving module 2 is used to be mounted on the equipment frame of the metal strip unwinding mechanism 7. More specifically, a set of linear modules can be used to achieve movement in the direction corresponding to the first direction, the direction perpendicular to the first direction and the horizontal direction, and a cylinder can be used to achieve movement in the vertical direction.

[0039] The output position of the three-axis moving module 2 has a second mounting part 2a, that is, the two sets of linear modules and one cylinder mentioned above drive the second mounting part 2a to move in the corresponding direction. The path of the second mounting part 2a in the first direction passes through the first mounting part 1.

[0040] Two gripper claws 3 are respectively installed on the first and second sides of the second mounting part 2a, with the first and second sides facing each other in the first direction. More specifically, a finger cylinder can be used as the gripper claw 3, and the installation method can be a fixed connection.

[0041] Please see Figure 3 The first finger cylinder 4 is installed in the first mounting part 1. When the first finger cylinder 4 is in the open state, both picking claws 3 can pass through the first finger cylinder 4, or the picking claw 3 near the metal strip unwinding mechanism 7 can pass through the first finger cylinder 4.

[0042] The metal strip unwinding mechanism 7 uses a torque motor and a magnetic powder coupler to drive the unwinding of the reel. After the metal strip 8 is pulled out from the reel of the metal strip unwinding mechanism 7, it is clamped by the first finger cylinder 4. The amount of metal strip 8 unwound is designed according to the position of the first finger cylinder 4, so that the metal strip 8 between the first finger cylinder 4 and the reel is in a taut or almost taut state.

[0043] The two gripper jaws 3 remain open, and the second mounting part 2a moves to the gripping position under the action of the three-axis module.

[0044] Regarding the statement that "both picking jaws 3 can pass through the first finger cylinder 4", at the clamping position, both picking jaws 3 are positioned between the metal strip unwinding mechanism 7 and the first finger cylinder 4. Accordingly: first, the two picking jaws 3 clamp the metal strip 8; then, the first finger cylinder 4 releases; next, the three-axis module drives the second mounting part 2a to move in the first direction, and the reel unwinds synchronously; finally, the second mounting part 2a moves to the shearing position and stops, ensuring that both picking jaws 3 pass through the first finger cylinder 4, and the reel stops unwinding synchronously.

[0045] Please see Figure 1 , Figure 3 and Figure 4 Regarding the aforementioned "the gripper 3 near the metal strip unwinding mechanism 7 can pass through the first finger cylinder 4", at the clamping position, the first finger cylinder 4 is positioned between the two grippers 3, and is located near the gripper 3 furthest from the metal strip unwinding mechanism 7. That is, the metal strip 8 completely passes through the first finger cylinder 4 and is then clamped by it, resulting in a small section of the metal strip 8 on the second side of the first finger cylinder 4 furthest from the metal strip unwinding mechanism 7. This small section is used for gripping by the gripper 3 furthest from the metal strip unwinding mechanism 7. During the back-and-forth movement of the second mounting part 2a between the clamping position and the shearing position, the gripper 3 remains clamped on the second side of the first finger cylinder 4 furthest from the metal strip unwinding mechanism 7, without passing through the first finger cylinder 4.

[0046] In some embodiments, it is preferred to use a method in which "the gripper 3 near the metal strip unwinding mechanism 7 can pass through the first finger cylinder 4".

[0047] This method makes fuller use of the metal strip 8 and reduces losses.

[0048] Please see Figure 1 and Figure 3 The scissor module 5 is slidably connected to the first mounting part 1 along a second direction perpendicular to the first direction. The scissor module 5 is also located on the second side of the first finger cylinder 4 away from the metal strip unwinding mechanism 7.

[0049] The first drive cylinder 6 drives the scissor module 5 to slide, causing the scissor module 5 to switch between two positions: a preparation position offset from the material clamping position of the first finger cylinder 4, and a cutting position coinciding with the material clamping position of the first finger cylinder 4. The first drive cylinder 6 can be a pneumatic slide table.

[0050] The scissor module 5 is in the ready position, and the second mounting part 2a is in the clamping position. Two gripping jaws 3 clamp the metal strip 8, and the first pneumatic finger cylinder releases the metal strip 8. The second mounting part 2a moves from the clamping position to the cutting position and stops, and the first pneumatic finger cylinder re-clamps the metal strip 8. The scissor module 5 moves from the ready position to the cutting position and operates, cutting the metal strip 8 between the first finger cylinder 4 and the gripping jaws 3 near the metal strip unwinding mechanism 7. The second mounting part 2a carries the cut metal strip 8 to the next process.

[0051] Please see Figure 6 and Figure 7 In some embodiments, the scissor module 5 includes: a fixed part 51 that is fixed in the cutting position and has a horizontal blade 51a, and a movable part 52 that is slidable relative to the fixed part 51 in the cutting position and has an inclined blade 52a.

[0052] Please see Figure 6 It can be that: the object to which the scissor module 5 is slidably connected to the first mounting part 1 is the fixed part 51, and the first driving cylinder 6 adopts a pneumatic slide table, so the fixed part 51 can be directly fixedly connected to the slide table; the movable part 52 is slidably connected to the fixed part 51, and a second driving cylinder 53 is provided between the two to drive the movable part 52 to slide relative to the fixed part 51. The second driving cylinder 53 can also be a pneumatic slide table.

[0053] Please see Figure 7 Alternatively, the object to which the scissor module 5 is slidably connected to the first mounting part 1 is the movable part 52, and the object to which the first driving cylinder 6 acts on the scissor module 5 is also the movable part 52. If the first driving cylinder 6 adopts a pneumatic slide, the movable part 52 can be directly fixedly connected to the slide. The fixed part 51 is slidably connected to the movable part 52 along the second direction, and an elastic element 54 is also provided between the two. The elastic element 54 can be a compression spring. The first mounting part 1 has a stop block 1a for the fixed part 51 to abut against and stay in the cutting position. The fixed connection position of the stop block 1a can be the cylinder body of the first finger cylinder 4.

[0054] Thus, during the movement of the scissor module 5 driven by the first drive cylinder 6: firstly, the movable part 52 and the fixed part 51 move together; then, the fixed part 51 abuts against the stop block 1a; then, the movable part 52 continues to move, overcoming the elastic element 54, while the fixed part 51 remains stationary. Compared to adding a second drive cylinder 53, using the first drive cylinder 6 to drive the scissor module 5 results in a simpler structure and more convenient control.

[0055] Please see Figure 1 and Figure 4In some embodiments, the second mounting part 2a is further provided with a tensioning cylinder 2b, which is used to drive the picking gripper 3 near the metal strip unwinding mechanism 7 to shift in a first direction. More specifically, the picking gripper 3 and the second mounting part 2a are mounted together by a linear guide rail, the cylinder body of the tensioning cylinder 2b is fixedly connected to the second mounting part 2a, and the piston rod is fixedly connected to the picking gripper 3.

[0056] After the scissor module 5 cuts the metal strip 8 between the first finger cylinder 4 and the picking claw 3 near the metal strip unwinding mechanism 7, the tensioning cylinder 2b drives the picking claw 3 to shift a little distance, increasing the distance between the two picking claws 3 and ensuring that the metal strip 8 on the two picking claws 3 is taut.
